rlhis invention relates to carriers of the` type used in conjunction Wit-h atrackele'- ment to slidably suspend curtains,draperies and like Window trimmings. i y

The principal object of the present invention is to provide a carrier embodying structural features, noise to the minimum, and which-permit the carrier to be movable or slidablefreely and easily, Without `possibility, of binding or impinging of portions of the carrier against portions of the trackelement.` f

Another object of the invention is to provide a carrier of the indicated character'embodying anti-friction balls on a carrier body so arranged with respect to the hanger also on the carrier body, to the pulling force exerted on the hanger, to the end that the carrier Will travel smoothly, and to'overcomebindingfor imdue to the carrier body moving relpinging atively to the anti-frictionballs. i

The nature of the invention and its distinguishing features and advantages Willappear when the following specification is read in connection with the accompanying drawing, in Which-4 Figure 1 is alongitudinal sectional vievvV taken centrally througha track element vand the carrier.

Fig. 2 is a transverse sectional vieW on an'enlarged scale taken on the line 2-`-2Ifof Fig. 1. i v i Fig. 3 is a plan vievvr `ofthe carrier.v

F ig. 6 is sec-tional vieW bakenen the lino 6-6 of Fig. 5. y

Referring now more particularly to,V the drawings, it Will be apparent that there has been shown infFig. 1 a track elnent 10 of a divided tubular construction, of angular formation in cross section so as to provide a top Wall 11, side Walls 12 and bottom portions 13 which provide tracks spaced from each other. The track element is secured by the use of suitable fastening` elements, such as the screws liwvhich respectivelyextend through holes in the top Wall 11, and take` into the head rail lpfor instance of a Window trame. suitable number of carriers which reduce friction and y l a hanger 18;

fopenings 19 to properly adjust itself v will be surrounded by caused to travel smoothly,

are used in conjunction with the track element for slidably` suspending a curtain or drapery. ln the presentinstance butone of such carriers is `shown, which will suliice to illustrate the present invention. It will be apparent, that eachcarrierwill comprise acarrier body 16, 'anti-friction balls 17, and the anti-'friction balls 17 and being carried by the carrier bodylb.` The carrier body 16 is produced from a blank, shown mostclearly in F ig. 4, ivhichfis stamped froml a singley piece of metal. Thesaid blank'as stamped, will have and 2O arranged in pairs and an opening 21 varranged centrally of the openings 19. The blank is bent on the dot and dashlines 22 so as to provide a plate member 23 and members 24 `directed inwardly over the plate member 23 in spaced relationship with respect thereto. This bending ofthe the hanger 18 occur in the plate` member 23. yThe hanger thevvall portion of the opening 21 a swivel connection.` The anti-friction balls '17 are alsofput -in place beforethe blankli's bent, there,beingone balll arranged in each of the" openings "19, so that when t-he members 24 are directed over the plate member 28, v each of the balls17 will be revolublyretainedpas shown most clearly in Fig. 2. It ivillxnoiv be understood that the hanger 18 17 at points radiating from the axis of the hanger 18. The carrier body 16 as formed,

Will be substantially square so that it may `blank is performed after the hanger 18 has `been arranged in the opening 21, which Will the anti-friction balls be arranged in the track element 1() with the v members 211 of the carrier body disposed longit-udinally or transversely, the result obtainedbeing the same in each case. The balls 17 roll :in contact in pairs respectively With the tracks 13, and due to the fact that the hanger 18 is arranged at a central point with respect to the balls, the Vcarrier Will be sibility of the carrier body 16 moving relaand Without pos-` tively to the balls 17, which might set upa j bindingy act-ion on portions of the carrier body With portions `of the track element 10, `when a pulling force is applied to t-he hanger 18. The contact of the portions of the carrier body 16 adjacent the side Walls 12 of the track element 10, .is negligible, when that Contact at two point-s ciated with the carrier Ebody 16 occurs. Inl Ythis form of .the carrier, the perimeter'fof efacli Ib all 1 7 may have rolling diaxnetrieally opposite each other. This rollingl contact, however, occurs at any givene i* i only, and nearly always occurs in conjunction with the related track 13, but may occur in conjunction with the top Vwall ll.

In the modificationillustrated in n) and 6,A .provision istmade vfor a three-point ,rolling contact ofk eachy of the antifriction balls.y In @accordance with this feature, the Acarrier body y1,6V instead of having pairs of spellings, .Such HS the Openings 19 anfl'QO. is lprovided jvith irregular openings which eX- ;tend vinto, the .plate member 23 and the members Q4. vWhen the members 24 `are. directed, inysjardlyI ,over the plate member 23 the balls 17,,\villbe revolubly Vretained asso- A i Each ball will be inrolling Contact with its related track member 13 when ,the Weight is on the hanger 25. Any upward movement of the carrier body 16 will cause rolling contact o tach lball with the top Wall l1 of the track .Q eilement. When there is any lateral pulling force .on the hanger 25 in one direction, there will be rolling contact between the balls at one side `oithe carrier body 16 and the adjacentv side Walls 12 of tbe ytrack element, andat the lsame time each ball will have yrolling contact with its related track 18. This form offcarrieris Substantially theysame asthefotherjorm, except that: each of the anti-triatlon balls isr capable of engagls the freek element any one of three points. Y. each case friction is reduced `A.to the minimum, and binding` or impinginget portions lis eliminated, and noise ,is almost entirely eliminated with the moditied form of carrier. Y

I claim: 1. A carrier Ifor the 'puiposespecified, oomprising a carrier bodyconsisting of a single .piece of material providing spaced retaining time at but. one pointportions, alianger connectedwith .the carrier body, and tanti-friction balls revolubly retained in place by said retaining portions and arranged around the hanger, there being a parrotthebarlls spaced from each other at i 4each side of the carrier body.

2. A carrier for the purpose specified, coniprising a carrier body, a hanger swivelly connected ivitlntbe lcarrier body, and antifriction balls revolubly arranged on thecarrior body around the hanger, there being a pair of the balls spaced from each other at each side of the carrier body.

l 3. A carrier for curtains and the ylike adapted Ato move within a divided tubular :track element, said carrier comprising a carrier bodyrconsisting of a single piece ot niafterial .providing spaccdretaining portions, a hanger-connected with `the carrier body, and anti-friction balls revolubly lield in Aplace by said retaining portions of Ithe carrier body, the balls being arranged spaced Afrom each other in .pairs at. opposite sides of the carrier body, .to yprevent tilting of the carrier body while in motion along the track element, as the result of a pulling force exerted on the hanger.

4,. A track type of carrier for supporting curtains and `the like, including a carrier body, 'and anti-friction ballsrevolubly arranged on the carrier body, there being a pair of 'tbe balls spaced gfrom each other at each side of thepcarrier body, the perimeter osteach ball occurring beyond the carrier body at diametrically opposite points.

5. The combination with a divided tubular track' element, of a carrier body movable 'withinvthe track element, and anti-friction bailsrevolubly arranged on the carrier body,

there Abeing a pair of the balls spaced from l' each other at each side ofthe carrier body, the perimeter of each ball capable of engaging the ytrack element at any one of three .points thereof in rollingcontact.
